Subject Re: [users@httpd] https redirect not being resolved as expected
Date Mon, 05 Mar 2007 17:22:18 GMT
Thanks for this. I tried the PT flag and it didn't make any difference. 
The disadvantage of not using mod_jk is that by using the http port of 
my app server in a rewrite it forces an external redirect and the URL is 
exposed to the browser which is not what I want....  Do I gather from 
what you're saying about the order that Apache tackles this that it is a 
no go ?
